Answer:

Option A ( -3/2 , $\frac{-3\sqrt{3} }{2}$ )

Step-by-step explanation:

According to Question, The Spinner Rotate 600* Thus after Completing 360* it Comes Exactly Where It Started . Now again rotate It 180* .

Now We Are on ( -X axis ) & Completed 360*+180*=540* Rotation

Now After Rotate It 60* More we come in Third Quadrant & Here In Third Quadrant Only Tangent & Cotangent Is Positive .(Sine & Cosine is Negative)

(For Diagram, Please Find in attachment)

Now In Triangle OAB

Cos60* = OA / OB

1/2 = -X / 3 Thus X= -3/2

Sin60* = AB / OB

$\sqrt{3}$ /2 = -Y / 3 Thus Y = - $\sqrt{3}$ * 3 /2

Let R be the triangular region in the first quadrant, with vertices at points (0,0), (0,2), and (1,2). The region R is the base

s2008m [1.1K]

The line through (0, 0) and (1, 2) has equation $y=2x$ .

Each cross section has a leg in the $xy$ -plane whose length is the horizontal distance from the $y$ -axis to the line $y=2x$ , which is $x=\frac y2$ .

The cross sections are isosceles right triangles, so the legs that lie perpendicular to the $xy$ -plane have the same length as the legs *in* the $xy$ -plane, hence these triangles haves bases and heights equal to $\frac y2$ . Then the area of each cross section is

$\dfrac12\left(\dfrac y2\right)^2=\dfrac{y^2}8$

where the cross sections are generated over the interval $0\le y\le2$ .

The volume of the solid is then

$\displaystyle\int_0^2\frac{y^2}8\,\mathrm dy=\frac1{24}y^3\bigg|_0^2=\frac{2^3}{24}=\frac13$

there are 4 red, 6 yellow and 6 blue socks in the drawer. if the sock is not replaced after it is drawn,what is the probability

ollegr [7]

Total amount: 16

Red socks: 4

Probability of picking a red sock 4/16

If we take a red sock out and do not replace it, we are left with a total of 15 socks.

Blue socks: 6

So the probability of picking a blue sock will be 6/15

Multiply:

4/16 * 6/15 = 24/240 = 1/10
